Tire tread



FIG. 1 is a fragmentary perspective view of a tire tread illustrating the novel design;

FIG. 2 is an enlarged fragmentary top plan view of the tire tread illustrated in FIG. 1;

FIG. 3 is an enlarged fragmentary side elevational view of the tire tread illustrated in FIGS. 1 and 2, with the opposite side elevational view of the tire tread being identical to that shown in FIG. 3; and,

FIG. 4 is an enlarged fragmentary cross-sectional view taken generally along lines 4--4 of FIG. 2.

The irregular outer edges of the design shown in FIGS. 1-3 indicate that the tire tread is of indeterminate length. 

We claim the ornamental design for a tire tread, as shown and described.
